本发明将喹唑啉结构与二苯醚结构相结合,设计并制备了一种结构新颖的4-氨基喹唑啉苯醚类化合物,可以有效防止害螨和小菜蛾等害虫,在相同的药剂浓度下,本发明式I化合物对螨卵的抑杀效果优于对照药剂螺螨酯,该化合物对小菜蛾等鳞翅目害虫也有杀灭作用。式I化合物的制备方法比螺环季酮酸类杀螨剂更加简便,生产成本更低,生物降解性好,环境污染小,是具有良好产业化前景的新型环保型杀螨杀虫剂。
本发明化合物在防治虫、螨及病害时,可根据实际需要既可以单独使用,也可以与其他杀虫、杀螨或杀菌剂等活性物质组合使用,以提高产品的综合性能。
本发明还包括以式Ⅰ化合物作为活性组分的杀虫、杀螨及杀菌组合物。该组合化合物还包括农业上可接受的载体。
本发明的组合物可以制剂的形式施用。式Ⅰ化合物作为活性组分溶解或分散于载体或溶剂中,添加适当的表面活性剂配制成乳油、悬浮剂、微乳剂或可湿性粉剂等。
应明确的是,本发明的权利要求限定的范围内,可进行各种变换和改动。
具体实施方式
下列合成实例及生测结果可用来进一步说明本发明,但并不意味着限制本发明。
合成实例:
实例1.化合物Ⅰ的制备:
(1)4-羟基喹唑啉的合成:
向250mL三口烧瓶中加入13.71g(0.1mol)邻氨基苯甲酸,加入27.0g(0.6mol)甲酰胺(溶剂/反应物),搅拌条件下加热至125℃,反应6h至邻氨基苯甲酸全部溶解,TLC法追踪反应至邻氨基苯甲酸反应完毕。待反应结束后,趁热将反应液倒入烧杯中,搅拌条件下加入50g水,降至室温产物大量析出,抽滤,用水洗涤,干燥得白色固体12.79g,收率87.6%。
(2)4-氯喹唑啉的合成:
向250mL单口烧瓶中加入29.2g(0.2mol)4-羟基喹唑啉,加入150g SOCl2(溶剂/反应物),搅拌条件下加热至回流,反应3h至4-羟基喹唑啉全部溶解,TLC法追踪反应至4-羟基喹唑啉反应完毕。待反应结束后,减压蒸馏除去多余的SOCl2。得到的黄色固体,用石油醚反复洗涤,抽滤干燥得淡黄色固体29.5g,收率89.7%。
(3)化合物Ⅰ的合成:
向100mL三口烧瓶中加入4.2g 4-(对甲苯氧基)苄胺(0.02mol),乙酸乙酯溶解后加入3.5g(0.021mol)4-氯喹唑啉,搅拌条件下加入3g(0.03mol)三乙胺,加热至回流反应2h,TLC法追踪反应,反应结束后,转移至烧杯冷却,加入50g水,继续搅拌0.5h后转移至分液漏斗中,分出有机层,水层用乙酸乙酯再萃取一遍,收集有机层,加入无水硫酸钠干燥后减压蒸馏,干燥,得白色固体5.5g,收率80.9%。
化合物Ⅰ的1H NMR(500MHz,DMSO-d6)δ:2.23(3H,s),4.66(2H,s),6.90-6.97(4H,6.94(ddd,J=8.2,1.8,0.6Hz),6.93(ddd,J=8.2,1.5,0.5Hz)),7.03(2H,ddd,J=8.2,1.0,0.5Hz),7.37(2H,ddd,J=8.2,1.0,0.5Hz),7.57(1H,dddd,J=8.2,1.5,0.5,0.5Hz),7.68-7.82(2H,7.73(ddd,J=8.0,7.4,1.5Hz),7.77(ddd,J=8.2,7.4,1.9Hz)),8.14(1H,ddd,J=8.0,1.9,0.5Hz),8.74(1H,d,J=0.5Hz).
生物活性测定:
实例2、式Ⅰ化合物杀螨卵活性试验
采用浸渍法和统计校正害虫死亡率的方法测定杀螨卵活性。具体过程是:将供试药剂按有效成分分别稀释至所需浓度,在无菌条件下各取50mL药液注入培养皿内,再分别浸入有朱砂螨卵(螨卵按室内标准化方法正常饲养的群体)的叶片,以添加50mL灭菌水的平板做空白对照。将培养皿放在24±1℃恒温培养箱内。48h后调查统计死亡率。每处理3次重复,结果取平均值,见表1。
表1式I化合物对朱砂叶螨卵试验结果
由表1试验数据可见,本发明化合物I具有优异的杀螨卵活性,在相同剂量下,化合物I的活性均高于或同于螺螨酯。
实例3、式Ⅰ化合物杀虫活性试验
杀小菜蛾活性测试方法:本发明化合物对小菜蛾活性测定采用国际抗性行动委员会(IRAC)提出的浸叶法。用配制好的待测药液,用直头眼科镊子浸渍甘蓝叶片,时间3-5秒,甩掉余液,每次1片,每个样品共3片,按样品标记顺序依次放在处理纸上。待药液干后,放入具有标记的10cm长的直型管内,接入3龄小菜蛾幼虫30头,用纱布盖好管口。将试验处理置于标准处理室内,48h检查结果以拔针轻触虫体,不动者为死亡。计算死亡率(试验做3次重复,取平均值)。
表2式Ⅰ化合物的杀小菜蛾活性测试结果
根据测试结果可知,本发明化合物Ⅰ对小菜蛾有优良杀灭效果。
